What is claimed is- 1. A coupling comprising an element having a recess in one side and opening through the end thereof, and a passage formed transversely and opening into the recess, the ends of the passage having continuous walls, and a second element comprising a stem and a head, the head being adapted to enter the recess and to be turned to lie in the passage with the stem projecting outwardly of the passage through the end of the first-named element.

2. Acouplingcomprisingan elomentadapted for attachment to an article to be coupled and having a recess in one face and opening through its end, a passage through the element opening into the recess, the ends of the passage having continuous walls, and a secf ond element comprising a stem having an enlarged base provided with a passage for the attachment of an article to be coupled and having a head, said head being adapted to enter the recess of the first element and to be turned therein to lie in the passage thereof, the stem being adapted to lie in the recess and to project outwardly thereof through the end of the first element.

3. A coupling comprising a block having intersecting passages, one of which extends through an end of the block, a follower disposed in the second passage, a spring for the follower, and a second element comprising a stem and a head, the head being adapted to enter one of the passages against the tendency of the follower and its spring, and to be turned to lie in the second passage and with its stem projecting outwardly through the end of the block.

4. A coupling comprising an element having a recess in one side and opening through the end thereof, a perforation in the element at the opposite end of the recess, a passage formed transversely and opening into the recess, the ends of the passage having continuous walls, a follower in the passage, a spring seated in the perforation and engaging the follower, and a second element comprising a stem and a head, the head being adapted to enter the recess and to be turned to lie in the passage with the stem projecting outwardly of the passage through the end of the firstnamed element.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two witnesses.

JOHN XV. PETTIJOIIN.
